Abstract
| - An organically templated titanium phosphate, (C6H13NH3)[Ti(HPO4)(PO4)]·H2O, has been preparedby hydrothermal synthesis from titanium(IV) chloride, phosphoric acid, and n-hexylamine. The structureof this material has been characterized by powder X-ray diffraction (XRD), 1H [including 1H{FS−Lee−Goldburg (LG)}−1H homonuclear correlation (HOMCOR), 1H double quantum (DQ), and 1H{FS-LG}−31P cross-polarization (CP) heteronuclear correlation (HETCOR)], 13C, and 31P magic-angle spinning(MAS) NMR, Fourier transform infrared (FTIR) spectroscopy, and thermal analyses [thermogravimetry(TG) and differential scanning calorimetry (DSC)]. Based on the empirical evidence, particularly solid-state NMR, modeling studies, and powder XRD, a crystal structure has been proposed, having unit cellparameters a = 5.089(2) Å, b = 6.335(2) Å, c = 22.792(5) Å, β = 102.48(2)°, space group P21, and Z= 2. This compound is built up of anionic titanium phosphate layers, similar to those present in theγ-type titanium phosphate, with n-hexylammonium cations intercalated in the interlayer space.
